Aurora Borealis over Northern North America and Canada
Video description:
This video was taken by the crew of Expedition 30 on board the International Space Station on January 29, 2012. This video begins as the space station is passing over the dark waters of the North Pacific Ocean northeast towards Vancouver Island. The Aurora Borealis can be seen far north, where both the under side and top of the aurora are visible. They continue to pass over Canada until the sun begins to come up in the east while over Quebec.

From NASA:
Sunset and twilight images are occasionally acquired by the science team to determine how high into the atmosphere the Martian dust extends, and to look for dust or ice clouds. Other images have shown that the twilight glow remains visible, but increasingly fainter, for up to two hours before sunrise or after sunset. The long Martian twilight (compared to Earth’s) is caused by sunlight scattered around to the night side of the planet by abundant high altitude dust. Similar long twilights or extra-colorful sunrises and sunsets sometimes occur on Earth when tiny dust grains that are erupted from powerful volcanoes scatter light high in the atmosphere.

The research was supported by the National Science Foundation, United States Air Force, Department of Energy and Beckman Institute.

Image description: In January 1984, Apple Inc. introduced a graphic user interface to its new computers. The idea had originated at Xerox’s Palo Alto Research Center in the 1970s, but Xerox was slow to commercialize it. Apple proved far more successful when it introduced the Macintosh with a splashy television advertisement during Super Bowl XVIII. The original price was around $2,500.
